At about 2:30, a hospital employee received a text message in Spanish. The employee did not know how to read Spanish, but she had it translated, and it was "deemed to be a threat towards the hospital employee," Davis wrote in a news release.

After investigating, however, Davis wrote, "we were able to gather enough information to believe that there was not an active credible threat, and the hospital was released from lock down and resumed normal operations.

"We will continue to investigate the incident, but at this time, it does not appear that anyone at the hospital is or was in any imminent danger," he wrote.
